After submitting the system, Tongzi and I became famous all over the world

Hearing this, Luosangsang frowned and thought for a moment, then shook his head, "I'm not sure, but we still have to be careful. I guess, besides the two of us, there should be other flying guests. Maybe they didn't come to scare us, but they went to scare that person!"

As they talked, they walked towards the stairs. Mu Yan stuck close to Luosangsang. Although she was still a little scared, she was more curious and excited at this moment.

Finally, the two of them successfully reached the stairs, walked down the stairs, and came to a hall.

But it seems that it is not on the first floor. However, since there are no stairs going downstairs, Luosangsang and the others can only walk towards the hall.

The hall was also pitch black. The windows around it were nailed shut with wooden boards, with only a few rays of sunlight coming through the gaps.

In the middle of the hall, there were some shabby furniture, medical equipment, and some simple fitness equipment.

The two of them looked at the things in the hall in the faint sunlight. Suddenly, Mu Yan kicked something, making a "clang" sound.

Following the sound, he saw another iron box. Luosangsang quickly squatted down and picked up the iron box. Like the first iron box, it was not locked.

Seeing this, Luosangsang quickly opened it, and inside the box was just as she expected, another photo and a rusty key.

Looking at the person in the photo, Luosangsang quickly recognized him. Before he could say anything, Mu Yan beside him exclaimed.

"Is this Brother Mu Jun? I didn't expect that the last guest star would be him."

"It seems that the program team wants us to rescue him. We don't know where he is. The program team just gave us this broken key and didn't give us any clues!" Luosangsang held the key and looked at it for a while, complaining.

"That's right, it's very bad. Let's look for other clues here. We don't know where this key opens!" Mu Yan complained helplessly.

Hearing Mu Yan's words, Luosangsang nodded. The two of them took the keys and looked around the hall.

I wanted to find the keyhole that corresponded to this key, but unfortunately I couldn't find it after searching for a while.

"Isn't it on this floor? Are we looking in the wrong direction?" Mu Yan looked at the key in Luosangsang's hand with some confusion, then looked up and looked around.

Upon hearing this, Luosangsang frowned, took the key, and searched the hall again, but still found nothing.

"I guess it's not on this floor. Let's go to other floors to check!"

"it is good!"

Mu Yan nodded in response. Just as the two were about to leave this floor, Mu Yan suddenly seemed to have thought of something and spoke to Luosangsang.

"Sangsang, do you think this key is not the key to open a door, but the key to open a cabinet? I just saw a medical cabinet over there, how about we go and try it?"

Upon hearing this, Luosangsang looked in the direction of Mu Yan's finger, and sure enough, in the corner of the hall, he saw a medical cabinet, not big, placed on top of a piece of equipment.

She had just seen this medical cabinet, but the first key was used to open the big iron door, so she thought the second key was used to open a big door and didn't think about it in other ways.

Now that Mu Yan has brought it up, we might as well give it a try. We can't miss any clues.

So he hurried over and inserted the key in his hand. With a "click" sound, the medical cabinet opened.

Luosangsang gave Mu Yan a thumbs up in surprise, then quickly opened the medical cabinet, which was filled with medical supplies.

But at the innermost part of the cabinet, there was a small wooden box, which Losangsang took out.

After opening it, I found a yellowed and worn piece of paper and an old map inside. The words on the note were a little blurred, but still legible.

"Mu Jun is on the B1 floor, go and rescue him quickly!" Mu Yan looked at the note and read out what was on it.

"Now that we know where it is, let's go there quickly!" Luosangsang took the map, looked at it carefully, and after determining the direction, he said to Mu Yan.

Mu Yan nodded after hearing this, and the two of them quickly closed the medical cabinet and walked towards the underground first floor following the instructions on the map.

Luosangsang led the way in front, and Mu Yan followed closely behind. Soon, the two of them reached the basement floor.

The environment here seems even more eerie and terrifying than the floors above, because on the surrounding walls are hung some diagrams of the structures of prosthetic limbs and human organs.

These may not seem like much at normal times, but in this dark underground floor, they look particularly scary.

Mu Yan tightly grasped the hem of Luosangsang's clothes and stared at his back, never looking to the sides. She was afraid of looking too much, so she didn't dare to move forward.

Luosangsang looked at her with amusement and had to drag her forward. The further they went in, the fainter "woo woo" sounds they could hear.

Hearing this subtle sound, Luosangsang took Mu Yan and walked forward quickly.

Soon, the two came to an iron door. At this moment, the iron door was closed, but from the gap in the door, they could vaguely hear sounds coming from inside.

Luosangsang frowned and looked at the iron gate in front of him. He was even more speechless about the program crew. Looking at the combination lock hanging on the door, he was silent for a moment.

"This is actually a combination lock. What's the combination? The program crew didn't even give us any clues!" Mu Yan looked at the combination lock in front of him and complained helplessly.

"That's right, let's think about what the password is! I guess it should be related to Mu Jun!" Luosangsang thought while trying several.

Unfortunately, none of them was correct, and the combination lock was still firmly locked. At this moment, Mu Yan seemed to have thought of something and said to Luosangsang.

"Sangsang, since the password is not about Mu Jun, do you think it could be today's date?"

Hearing this, Luosangsang's eyes lit up. He thought this was possible, and then he quickly pressed the number. With a "click" sound, the combination lock opened.

The two looked at each other and saw surprise in each other's eyes. They didn't expect that the password was set so simply. They just thought in the wrong direction at the beginning.

The two of them quickly took off the combination lock, pushed open the iron door, and walked inside.

Behind the iron gate is a short corridor, and at the end of the corridor there is a room. The sound also came from that room.

The door of the room was not locked and opened with a slight push.

Luosangsang looked at the empty room and Mu Jun, who was tied to a chair in the middle of the room with a piece of cloth stuffed in his mouth, and was speechless for a moment.

"Woo!"
